[c-nsp] Multilink Vs Serial Conf.

[Gangasagar Amula]

Dear All,

In our organisation.....we are using Multilink only for "fragment delay" feature of ppp multilink....

Hence we have configured one multilink for one link....

And we are facing a prb....i.e. if I am giving Fair-queue in Multilink and serial port...we get Queueing strategy: Weighted fair...
but in serial its "Queueing strategy: weighted fair  [suspended, using FIFO]"

Is it Multilink configuration prefered first and then Serial Link configuration....i.e. the fair-queue is really happening and then the data is thrown to serial as fifo....
Is it fair-queue doesnt happen twice....for same data....

Is my analyses to the observation right...?
Pls guide...
